Winter brings snow, ice and cold temperatures. Your car’s heating system is vital to your safety. It not only keeps you warm but keeps the windshield and rear window clear of ice, and from fogging up. Check all the functions of the heater and defroster. Make sure the heater fan motor is working on all speeds and make sure that the heater changes from the defrost mode, heater mode (floor vent) and regular vent. Move the temperature selector from cold to hot to insure that the heater system is responding correctly. Also, make sure that the rear defroster is working properly. If any of these functions are not operating properly, see your service professional today.
